IMPROVEMEN'T IN SHADE-GLDERS. -4 o The 'Schedule referred to in theseLetters Patent and making part of die rms.

To all whom 'it ma/y conce/rn:

Be it known that we, GEORGE H. DIMOND, GEORGE DOOLITTLE, and THOMAS B.DOOLITTLE, of Bridgeport, Fairfield county, in the State of Connecticut,

have invented a certain new and useful Improved- Shade-Holdem and we dohereby declare that the following is a full and exact descriptionthereof, reference being had to the accompanying drawings, making partof this application. f 4

Previous to our invention, it had been customary, in the use ofporcelain and glass (or other analogous material) shades for lamps andgas-fixtures, to support the slage upon bearings at thelower edge orbase of the s a e. l

There are obj ections to thus holding the shade, among which maybementioned, the obstruction by the supporting-arms of the light, thenecessary weight tothe lamp or fixture` of 'sucharms, and their cost;and lighter shades, of paper, &c., have been made, with spring-devicesat their tops, to claspto the chimney,

4 and thus avoid the objections to the base-supports and their necessaryappendages; but, previous to our invention, no means had been devisedlor suggested for connecting heavier shades, such as porcelain andglass, to the chimney ofthe lamp or argand gas-burner.

vQur invention has for its objects to provide a simple, economic, andefficient means (which maybe applied to all ordinary porcelain and glassshades now manufactured) of supporting such shades, from the top edge,on the chimney of a lamp or gas-,fixture and to this end,

Our invention consists in a metallic annular clasp, adapted to be sprungor clasped on to the top edge or anch of a shade, and provided with asuitable spring, or other means, for clamping it to the chimney of alamp or gas-fixture, as will be hereinafter more fully explained.

To enable those skilled Yin the art to make and use our invention, wewill proceed to describe it more particularly, referring by letters tothe accompanying drawing, in which- Figure l is an elevation of agas-fixture, chimney, and ordinary glass shade, with our inventionattached.

Figure 2 is a top .view of the holder, (or device for supporting orholding the shade on the chimney.)

Figure 3 is a partial vertical section through the holder and shade, atx x, iig. 1.

In the diiierent gures the same parts are designated by the same lettersof reference.

A illustrates a gas-fixture, provided with an argand burner, having theusual cylindrical chimney, B, on ,which is supported, by means ofourinvention, a glass or.' porcelain shade, C, of the-usual shape.

e is an annillar metallic' collar, of the shape, in crosssectionseen atg. 3, which is adapted to fit loosely over the top edge, ortlanch,.ofthe shade C, as seen at to collapse or spring back to itsnormal condition and natural diameter.

When the device, (seen at fig. 2,) thus composed of the ring e andsprings f, g, is placed or forced over the flanch, or top edge of ashade, C, the spring g. :fits into the concavity, near or under theflanch, or top lid of the shade, as shown at figs. l andy 3, andsecurely clasps itself to said shade, and the shade, with this deviceapplied to it, may then applied to the chimney, B, of a lamp orgas-fixture, as seen at g. l, by distending or stretching over saidchimney the ,spring-roll f.

It will be understood that the spring f will yield and adapt itself toany imperfection in the contour of the chimney, and to diametxicaldifferences in different chimneys of nearly the same size.

And. the same characteristic feature, it will be observed, exists inthemeans of attaching the device to the shade, so that the spring-clamp andholder, e f" g may be readily,- and with suicient security, attache v todifferent shades of nearly (though not exactly) the same size, and ofimperfect shapes at the top edge.

It will be seen that, although the holder-device is attached with asuliicient degree of permanency, for all practical purposes, to theshade, the top of the latter is free to expand and contract within thecoil-spring g, surrounding its topedge. Of course, by means of ourimproved spring-shade holder, the advantage is gained of the capacity toadjust the rigid shade to different heights on the chimney, ascircumstances .reqmre.

The springs f and g might either or both be made in sections, in lieu ofcontinuous, Without departing from the spirit of our invention, but wehave shown the apparatus or holder made as We have successllly used it,and as we deem it bestto be made.

Instead of the angular (in cross-section) collar e, a

metallic band of different shape might be employed, or

the springs f and g might have interposed some other medium ofconnection, which would still permit each to perform its function, (one,that of clasping the top of the shade, and the other, that of clampingon to the' chimney,) as described, and, in lieu of using the spring j,as shown, some other means of Securing the collar e at ,the desiredplace` around the chimney might be devised.

We do not wish to be understood as limiting our claim of invention tothe employment together of all the devices shown and described; buthaving fully described our invention, so that those skilled in the artor porcelain shade, of a holder, composed of a collar, e,

can make and use it, i provided with a spring, g, and a suitable meansfor What we claim as new, and desire to secure by Letclamping the collararound a chimney.
